Low Protien Diet Question

Hi all. My cat had 3 teeth pulled 2 weeks ago and he was doing great until
Thursday night when he started vomiting all over the place. Took him back to
the vet and was told that levels of something (sorry, I forget what the word
was) in his kidneys was a little high when they did blood tests. So he wants
Willie on a low protien diet. What I want to know is what is the best low
protien food (dry and wet) there is out there that I could start him on? Any
suggestions? Thanks for any help.

Nikki
